Application filed May a, 1920. Serial No. 106,258.

This invention relates to new and useful improvements in a hand tool.

One object of the invention is to provide a hand tool specially designedfor driving screw drivers, bits, reamers and the like, and having anovelly arranged grip member whereby the tool may be driven.

Another object of the invention is to provide a tool of the characterdescribed equipped with a novelly arranged grip member whereby the toolmay. be rapidly rotated and great power a plied to the work. With theabove and ot er objects in view this invention has particular relationto certain novel features of construction, operat-ion and arrangement ofparts an example of which is given in this specification and illustratedin the accompanying drawings, where- 1n:

Figure 1 shows a side elevation, partly in section, of one form of thedevice.

Figure 2 shows a cross sectional view thereof, taken on the line 2-2 ofFigure 1.

Figure 3 showsa side view of the implement of the general type shown inFigure 1, but having its shank equipped with a chuck for holding bits ofvarious kinds, and

Figure 4 shows a side view partly in section, of another type of tool.

Referring now more particularly to the drawings, wherein like numeralsof refer-' ence designate similar arts in each of the figures thenumeral 1. esignates the shank of the tool. As shown in Figure 1 thisshank terminates in a screw driver 2 which is integral therewith.

In Figure 3 the shank is shown as equipped with a chuck 4 to receive anytype of bit, reamer or other tool in the usual way.

' The other end of the shank has an ofi'set portion 4 forming a crank,and a handle portion 5 which is inclined with relation to the axial lineof the shank.

ed on the handle for ease in operation.

The angle of the handle 5, relative to the shank 1, is such that whenthe tool is rotated the axial line of the handle will describe thesurface of a cone, with its apex on 9 the axial line of the shank.

There is a grip member 6, rotatably mount- When the toolis applied tothe workjas for example a screw, the handle may then be swung around theaxis of the shank and the screw rapidly driven home or unscrewed.

Great power may be applied to'the work on account of'the leveragesecured, through dle 5 works. By applying pressure to the outer end ofthe plate 7 the friction of said plate with the handle 5- will hold theoperative end of the tool steady until it is engaged with the work. Thefriction plate 7 may then be released and the handle swung around itsaxis describing the surface of a cone, until the desired work isaccomplished.

In the form shown in Figure 4 the free.

end of the handle 5' is turned into alignment with the shank 1 andprovided with a butt 10 and there is a grip portion 11, arallel with theaxis of rotation of the s ank 1,

and located between the crank portion 4 and the handle 5. Thistype ofthe toolis adapted for use where great force is required, as for examplein l00sening nuts preparatory to unscrewing them, or m screwing nuts orbolts securely home, or for similar work. In such case the butt 10 maybe held in one hand, or against the body of the workman, and the gripportion 11 grasped by the other hand and the screw, nut, bolt, or thelike, loosened or securely driven home, and the remainder of the work ofunscrewing, or screwing up said nut, or the like, qu ckl accomplished bygrasping the grip 6', which is rotatable on the handle 5' and swingingthe same'around the axis of the shank, as hereinbefore described.

What we claim is: a

1. A hand tool including a shank .a handle, one end of which isconnected to but offset from said shank, a grip rotatable on the handleand a pressure plate carried by said tool and adapted to engage thehandle to hold the same against rotation relative to the grip.

2. A hand tool including a shank, a hangage the handle to hold itagainst rotation dle, one end of which is connected to and relative tosaid rip member. offset from the shank, said handle converging towardthe axial line of the shank, a mnames to this specification. 5 tatablegrip member carried by said handle and a friction member associated withthe FREDERICK ZELW'INSLOW, grip member and adapted to frictionally en-BOSE READER.
